  • Research summary

    BACKGROUND
    Stroke is a common and life-threatening condition. Almost 8 in 10 stroke survivors have visual perception problems such as difficulties with recognising objects or faces. These problems hinder stroke survivors in doing everyday tasks like driving, sending a text message or meeting friends. Diagnosis of visual perception problems is in the top 5 research priorities set by patients and clinicians.
    The available screening tools for visual perception problems are time-consuming. Therefore, clinicians most often have to rely on what patients report and on their own observations. Unfortunately, many problems are missed that way. A screening tool for visual perception problems is the first critical step to resolve the under diagnosis.

    We have developed a novel screening tool for visual perception problems. It has tasks such as naming pictures, recognising faces, and reading text. To our knowledge, our screening tool is the only one that is quick to administer, making it suitable for use in busy clinical settings and it is based on recent scientific insights on how the brain works.

    AIM
    We will now test if our screening tool gives similar results to the current best practice test (that is accurate but time-consuming).

    METHODS
    In this cross-sectional study, stroke survivors on rehabilitation units in the North East and Oxfordshire will be screened for vision, visual perception and cognitive difficulties with our screening tool and best practice vision and cognitive tasks. Sessions will take place within 14 days. They can be held on the stroke unit, their homes or through a video or telephone call as necessary.

    PATIENT BENEFIT
    In the long term, this will allow clinicians to quickly screen for visual perception problems after stroke and provide each patient with the best possible rehabilitation.
